C4H11ClNPS, also known as chlorpyrifos, is an organophosphorus compound that serves as an insecticide. It is a broad-spectrum pesticide used to control a variety of pests in agriculture, including insects, mites, and nematodes. Chlorpyrifos works by inhibiting the enzyme acetylcholinesterase, which is essential for the proper functioning of the nervous system in insects. This inhibition leads to the accumulation of acetylcholine, causing overstimulation and ultimately the death of the pest. The chemical structure of chlorpyrifos features a chlorine atom, a pyridinyl group, and a phosphorus atom bonded to an oxygen and a sulfur atom, with a butyl group attached to the phosphorus. It is important to note that while chlorpyrifos is effective, it is also toxic to humans and the environment, and its use is regulated in many countries due to concerns about its potential impact on human health and the ecosystem.

Check Digit Verification of cas no

The CAS Registry Mumber 3450-33-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,5 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3450-33:
(6*3)+(5*4)+(4*5)+(3*0)+(2*3)+(1*3)=67
67 % 10 = 7
So 3450-33-7 is a valid CAS Registry Number.
